Function capture_frame 

Source 
pub fn capture_frame(
    pixels: &[u8],
    width: u32,
    height: u32,
    format: PixelFormat,
    opaque: bool,
    turn: Turn,
    cover: (u32, u32),
) -> Option<CaptureFrame>
Expand description

The frame a view keeps of a width by height buffer of premultiplied pixels in format, which the compositor turned. With opaque, as in XRGB8888 and XBGR8888, the fourth byte is ignored. The frame is turned back upright and scaled down to frame_size for cover. None if pixels doesn’t hold width * height pixels.
